#### Answer

a) 2700
b) 66
c) 17
d) 1
e) 0 and 5 are relatively prime.
f) 210

#### Work Step by Step

To obtain the greatest common divisor of each pair of integers, multiply together the factors shared by both numbers.
a) $2^2\cdot 3^3\cdot 5^2=2700$
b) $2\cdot 3\cdot 11=66$
c) $17$
d) $1$
e) These numbers are relatively prime.
f) $2\cdot 3\cdot 5\cdot 7=210$
